On-board Computers

DSI OBCs pro­vide robust cen­tral com­put­ing to con­trol all the aspects of a space­craft. From teleme­try mon­i­tor­ing to sub­sys­tem con­trol, the OBC can be hot dual redun­dant to allow for extreme­ly high reli­a­bil­i­ty for the most crit­i­cal part of the space­craft avion­ics.

Fea­tures:

• Fault Detec­tion
• Space­craft Mon­i­tor­ing and Con­trol
• Time Man­age­ment
• EDAC Pro­tect­ed Mem­o­ries
• HK and TM Pro­vi­sion
  
• Space­craft Com­mand Exe­cu­tion
• Sin­gle Point Fail­ure Free Design

DSI OBCs are extreme­ly flex­i­ble, and can be out­fit­ted with a wide range of inter­faces and fea­tures, includ­ing with mem­o­ry func­tions if required.

Fea­tures:

• CPU Per­for­mance: 160 MIPS/FLOPS
• Redun­dan­cy: Cold or Hot Redun­dan­cy
• Con­fig­urable Inter­faces (SpaceWire, MIL-STD-1553B, RS422, Ana­logue mon­i­tor­ing, and more)
• Vol­ume: from 250 × 170 × 165 mm³ (L×W×H), depend­ing on unit
• Pow­er Con­sump­tion: from 15–25W peak, depend­ing on unit fea­tures
• High Reli­a­bil­i­ty: > 0.99
